I don’t have enough for a down payment but i do have quite a bit of equity in my home. looking for some insight on how i can get a low down payment or should i use my equity, plus funds to fix property.

I had just received a 30k down payment from another owner financed deal and I wanted to get a “second home” and get some additional rental income.

I say this because if there are repairs to be done, after closing costs and down payment, you won't have enough.2.

What investing method would you recommend to a first-timer and why?

I'm looking for LTR seller / owner finance deals that require $10k or less in down payment and that don't need much rehab (at maximum light rehab).

DSCR loans will likely require at minimum 1.00, so the monthly payment and rental amount would need to be equal or the rent higher.

Every time I rent to individuals less than that there are delinquent payment issues.

What we do on this case is lend up to 75% of the AS-IS value instead of using the purchase price for down payment.

You may need to put a little more of a down payment to get a nice building to break even but if you have enough income this may not matter as much to you.
