Does anyone have any resources or advice on how to know better about this?

& how you become financially free is by letting whoever your renting to (I'm guessing that was a step also?)

When relying on LIHTC to make the deal pencil, yes developers wait BUT only if they have the resources to wait and only if the property owner is willing to not close on the property until the project is fully funded.

Best case, you learn a lot, survive financially and trade up.

I am continuing to make payments on the existing mortgage from the payments received from my buyer, which I am assuming is a characteristic of a wrap-around mortgage where the seller acts as the financier for the difference between the existing mortgage and the sale price.

You'll need more capital and most will require a personal guarantee and personal financial backing. 

You and your legal, tax and financial advisors should review this transaction in greater detail, especially the PLRs, to ensure you understand the significant risks involved and are structuring the transaction as close as possible to the PLRs to mitigate some of the risks.

I lend money and would not want to lend on this type of deal.Here are some resources to explore:Contact your local tax authority ASAP!

We've found it's more capable than others when it comes to integrations, reporting capabilities, and efficiencies.The software you've mentioned will be better for the PM activities (property-specific transactions) than keeping up with your financials as a whole. 

I understand this is a good way to become financially secure over time and am eager to start.
