Here is the update after almost two years.
1. Building almost completed, so far cost $340K, I will also live on the first floor and it's interior cost $50K so the building cost is $300K and need another 50K to complete it,
Total 9 flat per flat $90 rent = $800 rent I will get per month.
2. Now I have more than 1 acre land ( cost of buying $120K, start doing Jujube farming, hoping will get per year $2K pure profit from it.
3. Have a land where I will build 5 small house after my building complete ( $50K land price and $20K house building cost)
and give rent $20 each, here I will get $100 per month.
4. Restaurant profit is lower now, around $200 per month.
5. Have a land ( buy with $25K)
where I will building 2 store ( required $5K to build)
and will get $40 per month rent.
So I will get around $1000 rent per month that cost me $450K to build. If I not build them and put all on bank, I will get $4K per month. But rent will increase day by day and also land value, and money on the bank will loss its value day by day, don't know whatever I make wise decision.
Restaurant investment only 10K and giving around $300 per month profit.
