I would strongly consider building equity to make a stronger down payment and further decrease your monthly cost. 

Please see the rough numbers below :Tear down house price 350k,Construction cost 165 sqft * 2 build=627k Darnell, did you get your questions answered?

Even 600k loan at 10% interest costs $165 a day.

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

This can put a significant strain on your finances and cash flowThey also often require a large down payment themselves and may have a strict repayment schedule that can be difficult to meet, especially if there are unforeseen circumstances or delays in renting the property or generating income from itIn addition, relying on this type of loan may expose you to higher financial stress and the possibility of default if you are unable to meet your loan obligationsThe final decision depends on your overall financial situation, risk tolerance, and your ability to manage the associated costs and obligations

@Hank Bank BRRRR is probably want you want to do.Buy, Renovate, Rent, Refi, Repeat.Before you go all in and either find out you don't like being a landlord or you make costly mistakes, start with just the next one.You'll have some challenges with tapping the equity in the townhouse:1) What loan amount can you qualify with your credit & income?

I have been told by many any raise under $50M do a reg c exemption and $50Mmis the cutoff for a reg a+ and $100M for a reit due to setup costs.

Of course there is also market opportunity cost to consider.

Just stating that waiting will also likely make the cost of what you want to buy go up if the last 98 years of real estate data provides the future direction.

At the end of the day, you won't make a pile of money, it will cost the developer more money than if they were just reasonable, and only the lawyers will be happy.
